This blog is to document my experiences with the Anet A8 3D printer; especially upgrading it and its parts.

There are at least a dozen articles and tutorials on the Anet A8 itself and its upgrades. I found that most of them are scattered or not detailed enough. Some are just lists of things to buy.

Hopefully you’ll find some good articles within this blog that’ll help you with your research on upgrades, materials and everything in between. There’s a quick FAQ for you at the end of this page.

Please bear in mind that you’ll have do disassemble and reassemble the printer a couple of time (at least the bed), depending on the upgrades that you are doing. It’s best to group them together as best as you can.

I do want to point out, that the printer I received worked like a charm straight out of the box. There were never any problems, fires, short circuits or any troubles to speak of.

However 3D printing is a game of patience and some prints take hours to complete. I never felt comfortable leaving the printer running over night; let alone when I wasn’t at home. Thus I want to stress the point that some upgrades are necessary if you’ve never printed anything with a 3D printer and don’t want to be spending 6 hours or more monitoring printer.


  • Anet A8 or Anet A8 Plus?

    The Anet A8 plus seems sturdier but I don’t have one. Just the old, regular Anet A8. I do intend however to upgrade the one I have with aluminium frames.
  • Do you have any other 3D printers?

  • Do I have to upgrade anything on my regular Anet A8?

    Yes. Most definitely some electrical parts, and at least the firmware.
  • How much did all the materials for all the upgrades cost?

    About 170.00 EUR – without the upcoming aluminium frame build.
  • Are all upgrades necessary?

  • What's the cheapest that I can get away with?

    About 90.00 EUR
  • Which upgrades do you recommend for someone on a budget?

    At least a MOSFET, Power-Supply, Power-Switch and a firmware Upgrade.
  • What is a MOSFET and do I need one?

    A MOSFET is a ‚Metal Oxide Semiconductor Field Effect Transistor‘. Yes, you need one. It prevents overheating, short circuits and your printer from cathing fire. It helps deal with the current drawn by your hotbed and hot end.
  • Why the firmware upgrade?

    It’ll catch a faulty sensor. Depending on which firmware your printer is running, you could run into trouble. There was a fully functional firmware shipped with the printer which didn’t check for a faulty temperature sensor. In certain cases the firmware did not recognize an increase in temperature to the desired level and it kept increasing the temperature, which in turn could burn down your printer and some things in the vicinity.
  • Why is upgrading the firmware so costly?

    It isn’t. It’ll cost you about 40.00 EUR. The firmware itself you can get for free along with the tools to build it. Getting the firmware on your printer’s board however requires some parts like the Arduino UNO (if you need to update the bootloader). Anything will do, but the estimate on the price is for the Arduino UNO, some capacitors and wiring. If you already have those it’ll cost you nothing but an hours‘ worth of work.
  • Do you review 3D printes?

    No. Not as of yet.
